anything actively sending out radiosignals is likely going to interfere with your beacon ...that being said the interference is usually negligeable ....
and about the recco things, do you carry a recco on your body when you go freeriding ? or only a beacon ? if you don't have a recco now your argument is pretty much invalid cause then it wouldn't change a thing.... (except the searchparty will now find a nice pair of skis)
and also, recco avalanche victim recovery is almost always too late ....
+ if you already have a beacon on yourself, that would be the first thing they would start scanning for, not recco ....
but yeah, i don't think it's going to be easy to 'borrow' skipatrol's recco finder to look for lost skis ....
